Remarks. Macrorhynchia philippina  , considered distinctive in traditional taxonomy largely on the basis of hydrothecal characters ( Fig. 22fView FIGURE 22), is thought to be essentially circumglobal in warm neritic waters ( Calder 2013). Molecular work on this hydroid has been limited, but thus far it seems to support the likelihood of a wide geographic range. Moura et al. (2012) discovered the same 16S genotype in hydroids identified as this species from two widely separated locations in the Atlantic Ocean ( Brazil and Madeira). In another analysis, the phylogram of Postaire et al. (2016), shows little intraspecific divergence in specimens assigned to this species from Moorea in the tropical western Pacific, from Juan de Nova Island in the Indian Ocean, and from the two Atlantic populations mentioned above.

Several records of M. philippina  from the western North Atlantic require comment. Although the species is known to occur in Bermuda (Calder 1997), Congdon’s (1907) record of it from there (as Lytocarpus philippinus  ) is based, at least in part, on a misidentification ( Bale 1919: 352; Stechow 1920: 44; Calder 1997: 68). As evidence of this, an illustration of the species ( Congdon 1907, fig. 37) portrays M. allmani ( Nutting, 1900)  instead. It is likely that specimens collected nearshore were M. philippina  , while those from Challenger Bank were M. allmani  . Records of M. philippina  from Bermuda by Smallwood (1910) and Bennitt (1922) are somewhat uncertain given earlier confusion over the species in the area. Nutting (1900) reported M. philippina  from Panama, but he failed to indicate whether the hydroids he examined were from the Atlantic or Pacific coast of that country.

More detailed accounts of this species in the western North Atlantic are given elsewhere (Calder 1997, 2013). An extensive synonymy list under M. philippina  appears in Ansín Agís et al. (2001). Gonophores are liberated as short-lived medusoids ( Gravier 1970; Migotto 1996; Bourmaud & Gravier-Bonnet 2004; Galea 2018).

Reported distribution. Gulf coast of Florida. Dry Tortugas ( Wallace 1909: 137, as Lytocarpus philippinnus  ).
